What is the maximum length of a Window's command-line (cmd.exe) command?

Question

There are many people asking questions on SO about how to get around the cmd.exe command maximum length. I was wondering what actually is the Windows command-line length limit? Is it different between version of Windows? Does using a 32-bit vs. a 64-bit version affect this limitation?

The first result of asking google about your question was this MS Knowledge Base article:

On computers running Microsoft Windows XP or later, the maximum length of the string that you can use at the command prompt is 8191 characters. On computers running Microsoft Windows 2000 or Windows NT 4.0, the maximum length of the string that you can use at the command prompt is 2047 characters.
